Let's divide 590723 by 19
The aim is to understand the frequency of 19 in 590723.

Advancing to step 1:
When dividing 5 by 19, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 19

Advancing to step 2:
The number 19 fits into 59 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 2 after subtracting 57 from 59.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 19

Going ahead to step 3:
The number 19 fits into 20 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 1 after subtracting 19 from 20.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 19

Going ahead to step 4:
When dividing 17 by 19, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 310.0
If we subtract 0 from 17, we get 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 19

Let's proceed to step 5:
172 divided by 19 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 3109.0
Subtract 171 from 172 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 19

Advancing to step 6:
13 divided by 19 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 31090.0
Deduct 0 from 13 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
19 goes into 130 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 31090.6
Deduct 114 from 130 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
When dividing 160 by 19, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 31090.68
If we subtract 152 from 160, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
19 goes into 80 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 31090.684
Deduct 76 from 80 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 19, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 31090.6842
If we take 38 away from 40, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
19 goes into 20 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 31090.68421
If we subtract 19 from 20, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
19 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 31090.68421
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
When dividing 100 by 19, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 31090.6842105
Deduct 95 from 100 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
19 goes into 50 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 31090.68421052
If we take 38 away from 50, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 31090.68421052 and a remainder of 1.2e-08.
